In the following manual labour, we go on the search to work 2 (two) dimensions, which we consider them complementaries in the affirmation of the cultural subject: A dimension centered on the subject itself. How can the subject be affirmed on itself like a "valuable" one; that is to say, what Arturo Roig denominates the "anthropological a priori". A dimension focused on the conditions of possibility of emergence of this subject. The projection on the part of the "other", of the educative community, of the subject like a "valid interlocutor" with its origin in the positions of the critic theory (Adela Cortina, Habermas, Apel). This second dimension will develop an ample fan of experiences, like posibilitators to form the valuable one. In this sense, it is proposed to develop the following concepts: -The construction of I, -The self-concept, -The self-steem. Likewise, it is outlined that the cultural subject is to develop a new relation with the language, that is he will advance from his pre-reflexive use, like an instrument typical of ethics, towards a critical use. Searching to potencialize his load, decisive of conflicts as its communicative and emancipatory functions.
